Cellulose is “green.” It’s made of 80% post-consumer recycled newsprint. The fiber is chemically treated with non-toxic borate compounds (20% by weight) to resist fire, insects and mold.. Cellulose earns “green” points because it requires less energy than fiberglass to manufacture. Disciples claim 200 times less petro-energy than fiberglass.
More realistically, Environmental Building News reports that fiberglass requires approximately 8 times more energy to make when adjusted to reflect energy cost per installed R-value unit.
